Key specifications at a glance

• Amperage: 30A
• Poles: 3-Pole
• Voltage: 240V
• Reference part number: AC321I

Why this fusible bus plug stands out

• Exact-fit compatibility — designed to match GE switchgear configurations, ensuring a reliable electrical connection and predictable performance in service conditions.
• 3-Pole design for 3-phase systems — optimized for circuits that require three simultaneous, protected conductors, helping maintain balanced protection across phases.
• Maintenance-ready — a practical choice for service crews performing routine maintenance, panel retrofits, or part replacements without overhauling the entire assembly.
• Clear compatibility reference — the part number AC321I is the best reference for verifying fit and ratings before ordering, reducing guesswork and downtime.

Ideal use cases

• Downtime planning for routine maintenance on GE panels or switchgear where a fusible bus plug is required
• Retrofit projects that update protection schemes without changing the entire bus interface
• Replacement during field service to restore original protection characteristics quickly

How it helps you work smarter

• Minimizes troubleshooting time with a clearly defined 30A, 3-Pole, 240V specification aligned to a known GE configuration
• Reduces risk by providing a matched, fusible connection that preserves intended protection levels
• Supports proactive maintenance planning by offering a dedicated, compatible bus plug option rather than improvised substitutions

Practical tips for best results

• Before ordering, verify that the panel or enclosure requires a 30A, 3-Pole, 240V fusible bus plug and that AC321I is the correct GE reference for your configuration.
• Keep spare bus plugs in a dry, protected area to prevent corrosion and ensure quick swaps during maintenance windows.
• Consult your facility’s electrical schematics and the panel’s documentation to confirm the exact fit and ratings, using the AC321I part number as your compatibility guide.
